THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 375,643, dated December2'7, 1887.

Application filed September 9, 1887. Serial No. 249,239. (No model.)

To all whom it mag concern:

Be it known that I, TARGE G. MANDT, a citizen of the United States, anda resident of Stoughton, in the county of Dane and State of Wisconsin,haveinvented certain new and useful Improvements in ThillCouplings; andI do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which- Figure l is a side view of my improved thillcoupling. Fig.2 is alongitudinal verticalsectional view of the same, and Fig. 3 is atransverse vertical sectional view.

Similar letters of reference denote 'corre sponding parts in all thefigures.

My invention has relation to anti-rattling thill-couplings, and moreparticularly to the manner in which the spring, which will behereinafter more fully described, is secured to the clip.

In the accompanying drawings, the letterA represents the axle, to whichthe clip B is secured. This clip is provided near its rear ends withregistering apertures, while its upper portion or jaw is formed with aflange, 0, upon each side thereof. The box D is formed integral with theforward end of the clip, and is provided at its forward end with a shortcircular cross-rod or bearing-pin, E, and at its under side with a largeaperture, E, the oloject of which is to permit the escape or removal ofdust or dirt, which is apt to accumulate in the box.

F denotes the spring, having its forward end curved, as shown at G, andprovided with an aperture, H, which, when in position, registers withthe apertures in the rear portion of the clip. This spring is secured,with its straight rear portion against lateral displacement, to theupper jaw of the clip, between the flanges thereof.

The clip is secured to the vehicle axle, which is filed away to producea rounded surface, (shown at 1,) by means of a bolt, J, passing throughthe apertures in the jaws of the clip and the aperture of the spring,and a nut, K, screwed upon the lower screw-threaded end of the saidbolt. The thill-hook L, to which the thill is secured, is hooked to thebearing-pin E and above the forward curved end of the spring.

It will be seen that the spring will force the thill-hook firmly againstthe bearing-pin, thus preventing it from rattling, and it will also beseen that by forming a rounded surface upon the axle this spring will beallowed a greater vertical play.

, From the foregoing description, taken in connection with theaccompanying drawings, the operation and advantages of my invention willbe readily understood without requiring further explanation. It issimple in construction, inexpensive to manufacture, and the thillhookcan be easily and quickly attached to or detached from the clip, ifdesired.

Having thus described my invention,I claim and desire to secure byLetters Patent .of the United States 1. In a thill-coupling, thecombination of a clip having flanges integral with the upper jaw of thesame, with a curved springinclosed within said clip and retained againstlateral displacement by said flanges.

2. In a thill-coupling, the combination ofa clip having the edges of oneof its jawsflanged, registering apertures in said jaws, a boxingintegral with the forward portion of the clip, said boxing provided witha bearing pin or rod and having an aperture in its under side, a springhaving its lower end curved and its upper end formed with an apertureregistering with the apertures in the clip, bolts passing through theapertures of the clip and the spring, a nut screwed upon the end of saidbolt, and a thill-hook.

3. In a thill-coupling, the combination of a vehicle-axle, a portion ofits forward upper edge formed rounded,with aclip,substantially ashereinbefore described, a spring inclosed by said clip and bearing withits intermediate portion against the said rounded edge of the axle,which permits of the said spring having a vertical play, and means forsecuring the clip to the axle.

In testimony thatI claimthe foregoing as my own I have hereunto affixedmy signature in presence of two witnesses.
